I have a Powershot A40, and I'm very happy with the shutter speed control and the aperture control either, but I was trying to take some pictures with the object in foreground sharp and all the background very blurry, but i just can't!! The whole scene comes out sharp, or just a little blurry.. I use the Manual mode, set the Aperture to 2.8 (the biggest) and use the autofocus on my subject!
Anyone knows if I can take that kind of shots with my camera??
Thanx a lot!!

How far away from the subject is the background? The further away the better. Also, digi dof is greater at 2.8 than a traditional film cam at 2.8.

hovland,
I had the same problem with my camera when I was learning about Manual mode photography.
What is happening is that you probably have your focus set on infinity (landscape focus). There are three focus settings for the camera that need to be selected before you take your shot: macro, portrait, landscape (infinity).
Autofocus doesn't mean that the camera will select these setting automatically in Manual mode - you still have to pick one of the three focus ranges above. The autofocus you mentioned is in actual fact the range finder, I believe.
As far as the blurry background goes, shooting in Macro mode will give you the best results. Portrait will work for short range object objects, as long as the background is far away.
Good Luck
Calaille. |

| try the largest aperture at full telephoto with the subject as close to the camera as possible while still being in focus. that'll give you the best possible results. the focus may 'hunt' for a while so take a lot of shots. |

I do not know the optic rules but unfortunatly it's not easy to get it with a digital camera that is not a SLR unless you have a very high focal.
The 'blurry background' does not come only from focal and aperture but as well wil the diameter of the front lens.
Again I do not know the theory but 100mm at 4 on a SLR is going to give you a blurry background that you're not going to get on a digital camera, even if you have manage to have 100mm equivalent at aperture 4. |

This is where digital post-processing makes life a snap.

Lionel,
I feel your pain. In shooting with the Nikon 995, I face the same "small front element" issue. If you want the DOF, great, but I'm still wishing I can get the same control over DOF as with my ol' Exakta, and it just ain't happening.
Another reason to upgrade to DSLR... someday. |
